ACETYLEN E-LAM P.

SPECIFICATION forming part of Letters Patent No. 738,549, dated September 8, 1903.

Application filed March 21, 1902 Serial No. 99,332. (No model.)

To all whom it may concern;

Be it known that I, J OHANNES ALEXANDER KRUSEMAN, a subject of the Queen of the Netherlands, residing at Gracht 219, Lisse,

Holland, have invented certain new and useful Improvements in Acetylene-Lamps, of which the following is a specification.

This invention relates to acetylene-lamps, and has for its object improvements in the admission of air to the flame, so that it may be regulated or partially interrupted according to the strength of the wind, and also in the attachment of the carbid-container to the lamp and the admission of water to the container.

In the accompanying drawings, which illustrate the invention, Figure 1 is a side elevation of the lamp. Fig. 2-shows a section on the line A B of Fig. 1. Figs. 3, 4, and 5 show details of construction.

The lamp consists of an upper part comprising the burner, reflector, and water-reservoir and of a lower part which contains the carbid. These two parts are conveniently connected as follows: The upper portion has a neck 1, theupper part of which is conical and the lower part cylindrical, and the upper part carries the burner 2. This burner is inclosed by a hood 3, which forms also the reflector. The burner 2 enters the hood 3 through an orifice 4 in the latter. A side or wall 5 rises from the conical part of 1 and forms with the hood 3 a chamber or channel 6, throughwhich air is admitted to the flame. The upper part of the hood 3 has an opening 7, which is adapted to be covered by a cap 8 in such a manner that air may pass freely to the interior to the hood 3 or that air may be excluded therefrom, so that the air-current may be regulated by a simple movement to insure the steady burning of the flame. The

ends of the cap 8 are bent off at both sides in the form of a step, the vertical part 10 of which slides in guides 11. The horizontal part 9 of the step of the capS covers the admission-orifice to the chamber 6 when this cap has been pressed down, so that no'air can pass into the chamber. Simultaneously the curved part of the cap 8 covers the opening 7 in the hood 3. In order that the necessary air may be admitted to the flame when the cap 8 has been fully pressed down, the door of the lamp, consisting of a metallic frame 12 holding a pane of glass, is constructed as follows: The metallic frame 12 is of larger diameter than the front frame of the reflector and is pivoted to the hood 3 by means of a hinge 14. The pane is situated in the bent-over edge of the frame 12 and is held there by lugs 15, soldered or braced to the frame 12. Any convenient number of lugs may be provided which prevent the pane being in direct contact with the front frame of the reflector-casing or hood 3, so that a channel is formed between this and the pane of glass which admits air from behind without the door being able to rattle and obviates gusts of wind reaching the flame. The lower edge of neck 1 is formed as a bead containing a wire insertion 16, which is provided with two loops 17 at opposite points, with which correspond vertical slots 18 (shown in dotted lines in Fig. l) in the cylindrical portion of the neck 1. The lower part of 1 thus formed is surrounded by a ring 19 (illustrated in Figs. 3 and 4) and provided with two oblique slots 20 and looper portions 21, corresponding with the loops 17 and designed to passover the latter when the ring is placed into position. The part 22, which is designed to contain the carbid, is provided with two pins 23, also at sides opposite to each other. These pins are carried through the loops 17 and 21, so that they are at the level of the lower end of the slot. The ring 19 is then turned relatively to the body of the lamp, consisting of the upper part, and the carbid container and the oblique slots 20, engaging with the fixed pins, draw the upper and lower parts of the lamp together, the joint being rendered air-tight by a rubber ring 24, provided in the interior of the upper part.

The carbid-container 22, as shown in the drawings, is formed cylindrical and with a bead at its upper rim. A partition 25 is divided into two parts, each of which has a chamber 26, separated from it by a semicircular sieve. This division is arranged so that the carbid in the container is not acted on at once, but in portions.

The admission of water takes place from a water-reservoir 27 arranged in the upper part and provided with a dripping-valve in The water passes through theusual manner.

a tube 28 to a small pipe 29, which is provided in the conical portion of the neck 1 i and extended therein and bent so that its I have described hereinbefore as an example how my invention maybe carried into efit'ect; but I may modify the construction in any manner.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. The herein-described. acetylene-lamp consisting in combination of an upper part comprising the burner, reflector and waterreservoir and a lower part comprising a carbid-container, a hood 3 forming the reflector and provided with openings 4 and 7, aburner passing through opening 4 and a side or wall 5, a channel being provided between said wall 5 and the hood 3 for the admission of air, substantially as and for the purpose set forth.

2. The herein-described acetylene-lamp consisting in combination of an upper part comprising the burner, reflector and waterreservoir and a lower part comprising the carbid-container, a hood 3 forming the reflector and provided with openings 4 and 7, a burner passing through opening 4, a side reams or wall 5, a channel being provided between said wall 5 and the hood 3 for the admission of air, and a cap 8 with ends 10 adapted to close the opening 7 and the openings in the channel 6, substantially as and for the purpose set forth.

3. In an acetylene-lamp, the combination of a casing, a door hinged to the front of the Y casing and consisting of a ring of larger diameter than the front of the casing and into which the edge of the casing enters, a glass pane in the ring and spacing-lugs inside of the ring preventing the ring from resting against the edges of the casing and provid-.

ing a space or passage around the rear edges of the ring for the admission of air, substantially as described.

4. In an acetylene-lamp, the combination of an upper part and a lower part partially telescoping each other, one of the parts carrying pins passing through slots in the other part, a packing-ring inserted between the parts and a ring having oblique slots into which said pins project whereby in turning the ring, the parts are drawn together to seal the joint between them.

In testimony whereof I have hereunto set my hand in the presence of two witnesses.
